t^{2}-5t-36=0
Whakakapia te t mō te x^{2}.
t=\frac{-\left(-5\right)±\sqrt{\left(-5\right)^{2}-4\times 1\left(-36\right)}}{2}
Ka taea ngā whārite katoa o te momo ax^{2}+bx+c=0 te whakaoti mā te ture pūrua: \frac{-b±\sqrt{b^{2}-4ac}}{2a}. Whakakapia te 1 mō te a, te -5 mō te b, me te -36 mō te c i te ture pūrua.
t=\frac{5±13}{2}
Mahia ngā tātaitai.
t=9 t=-4
Whakaotia te whārite t=\frac{5±13}{2} ina he tōrunga te ±, ina he tōraro te ±.
x=-3 x=3 x=-2i x=2i
I te mea ko x=t^{2}, ka riro ngā otinga mā te arotake i te x=±\sqrt{t} mō ia t.
t^{2}-5t-36=0
Whakakapia te t mō te x^{2}.
t=\frac{-\left(-5\right)±\sqrt{\left(-5\right)^{2}-4\times 1\left(-36\right)}}{2}
Ka taea ngā whārite katoa o te momo ax^{2}+bx+c=0 te whakaoti mā te ture pūrua: \frac{-b±\sqrt{b^{2}-4ac}}{2a}. Whakakapia te 1 mō te a, te -5 mō te b, me te -36 mō te c i te ture pūrua.
t=\frac{5±13}{2}
Mahia ngā tātaitai.
t=9 t=-4
Whakaotia te whārite t=\frac{5±13}{2} ina he tōrunga te ±, ina he tōraro te ±.
x=3 x=-3
I te mea ko x=t^{2}, ka riro ngā otinga mā te arotake i te x=±\sqrt{t} mō t tōrunga.
